PUMPING-ENGINE REGULATOR.

SPECIFICATION forming part Of Letters Patent N 0. 652,347, dated June 26, 1900. Application filed February 1,1899. Serial No. 704,083. (No model.)

To all whom it ntcty concern:

Be it known that I, JOSEPH H. CHAMP, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented a new and useful Improvementin Pumping-Engine Regulators, of which the following is a specification, the principle of the invention being herein ex plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions. 1

The object of the invention is to provide improved means for automaticallycontrolling the flow of the energizing fluid relative, to a pumping-engine."

The invention consists of the means hereinafter described, and particularly pointed out in the claims. The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be use a Figure I is a side elevation representing the regulator, pumping-engine, and tank, to gether with connecting-pipes. Fig. IIjis a sectional elevation of the regulator looking toward its induction-port of said energizing fluid. Fig. III is a sectional elevation of the regulator looking toward its eduction port of said energizing fluid. Fig. IV is a view in sectional elevation of the regulator in a plane at right angles to the and III are taken.

Fig. V is a plan view of the regulator.

Water under pressure passes from a water-' main through induction-port A into regulator B, connecting by passage a with annular channel I). Therefrom pressure-water may pass through port 0, when the latter is open, into main-valve chamber 0. But whether said port 0 be openor closed pressure-water passes from said channel b to channel d and into ring-chamber d, thence into auxiliary-valve chamber D, this auxiliary-valve chamber D being always in communication with such pressure-water, and, hence when valve '1" is below ring-chamber d the pressurewater maypassthence through channel 6 into piston-chamber E at a point always below plane in which Figs.

the piston. Packing-ring r is rigidly secured to'valve-stem R at such a point thereon as to cause such packing-ring to be always above ring-chamberd, such packing-ring constituting. the upper end of the auxiliary-valve chamher D and movable correspondingly with s'aidvalve-stem and with the central portion 1 of diaphragm P, which is rigidly secured to such valve-stem above said packing-ring, the

construction being such as to prevent any fluid within the auxiliary-valve chamber from passing into chamber p, within which diaphragm'Rworks, When port 0 is open and piston F has pressure-water on both its upper and under faces, main valve G then has pressure water only against its under face, and

is therefore effectual to maintain itself and piston F in raised position, such piston being secured to the lower end of valve-stem 0'.

Said main-valve chamber and piston-chamher are in constant open communication with eachoth'er'. The opposing faces of the main valve and the piston are always subject to the same fluid-pressure, and fluid-eduction port His constantly in open communication with the piston-chamber at a point always above the piston, the pressure-water within valve-chamber O therefore finding exit from the regulator through eductionport H and thence by intermediate connection H topumping-engine K and after operating the latter such water passing away through pipe L. The pumping-engine thus operated by said pressure water takes cistern-water through pipe M and forces same out through pipe M into tank 0. This tank 0 is provided with a close top 0 and with a discharge} pipe of at its bottom, such discharge-pipe having communication with the distributing system of cistern-water servicepipes throughout the house. As the cisternwater enters the tank the air confined in the lower portion of the latter is correspondingly displaced and rises into the upper portion of the tank in compressed form, such compressed volume of air acting in elastic pressure upon the cistern-waterin connection with its distri- When the tank becomes sufficiently filled with cistern-waterto cause back pressure of the cistern-water in pipe N, communicating with pipe M, port N, and

- tern-water is sufficient to overcome the tension of the adj ustably-set spiral spring 1:) then the diaphragm P is raised, carrying with it the valve-stem R, to which are secured the valve 7 and the packing-ring r, the central portion of the diaphragm being rigidly se cured to the valve-stem, so as to move together either up or down. This valve-stem movement carries valve 1' above ring-chamber (1 thereby cutting off the under face of piston F from the pressure-water and throwing said piston-face into communication with the waste-port S, whereupon the pressure of supply-water against the upper face of piston F overcomes the pressure of supply-water against the under face of main valve G, and said main valve and piston thereupon start in downward movement, causing such valve to shut off the supply-water from entering into valve-chamber 0 through port a.

This necessarily shuts oil? such supply-water from passing out from said valve-chamber 0, through port H, to the pumping-engine K, and thereupon the latter ceases its work of forcing cistern-water into tank 0. After cistern-water has been drawn from tank 0 sufficiently to reduce the back pressure of the cistern-water against the under face of diaphragm P to enable spring 19, as tensioned by screw-cap 19 to again become effectual, then such spring forces the central portion of said diaphragm downward, together with valve-stem R. Such downward movement of said valve-stem carries valve r below ringchamber d thereby cutting off the lower face of piston F from communication with the waste-port S and restoring such piston-face in communication with the supply-water by means of channel e, ring-chamber d auxil-.

iary-valve chamberD, ring-chamber d, channel d, annular channel I). Main valve G thus becomes effectual to raise itself and piston F, the two being rigidly secured to mainvalve stem 0, again permitting the supplywater to pass out through port 0 into mainvalve chamber 0, when the first-described operation of parts obtain, and the supply-water passes through port H to pumping-engine K and causes the latter to resume its work of pumping cistern-water into tank 0.

While I show in this instance the energiz ing fluid of the pumping-engine as being water under pressure, it is apparent that the same construction and operation would obtain in using steam, compressed air, or other fluid as the energizing fluid. Such energizing fluid is absolutely and completely out off from the pumping-engine, so that there is no delicate balance between supplying the ener gizing fluid and cutting the latter off. EX- perience and long practice show that it is impossible to maintain valves of a pumpingengine in such order that they will not permit of some leakage of the energizing fluid into the pumping-engine, provided the pres sure of such fluid is maintained against such valves when the tank is filled and the pumping-engine should be at rest. Such leakage cannot obtain according to my invention, and when the tank is full and the pumping-engine should therefore be completely at rest its valves are absolutely cut off from pressure of the energizing fluid.

In addition to the foregoing my invention presents means adapted to insure the automatic resumption of the eduction of the energizing fluid from the regulator when the tank is prepared to receive further supply of cistern-water, so that such nergizing fluid is without interyention of an attendant let on again to tlfe'pumping-eiagirie at the timewhen the lattershould recommence pumping scistern-water into the tank.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means covered by any one of the following claims beemployed.

I therefore particularly point out and distinctly claim as my ii1ventio1r l. The combination of a main-valve chamber and a piston-chamber connected together in constant open communication with each other, a main valve and a piston connected together and respectively working in said two chambers, an induction-port controlled by said main valve and adapted when open to permit fluid to pass between the opposing faces of itself and said piston, an eductionport, an auxiliary valve connected to a movable device in a fluid-pressure chamber and adapted to control communication of fluid relatively to the remaining face of said piston, substantially as set forth.
